Using search engines such as Google plays an increasingly valuable role in the research process, and can alert you to material you would not otherwise come across. When you use freely-available websites, though, you have to be responsible for judging the authoritativeness and quality of what you are seeing, and you will (for the most part) only see what can be offered for free. Libraries have shared buying power and can make available full-text of articles that come through reputable publications that have some kind of editorial review process in place.
